Owners of the Houston’s restaurant chain plan to open a new eatery, the East Hampton Grill, on Memorial Day weekend after taking over the Della Femina space. Although ad legend and eatery owner Jerry Della Femina told another paper yesterday he’s only “in talks” with Hillstone Restaurant Group and claimed his famed North Main Street power spot “has not been sold,” a Hillstone rep tells us the name and opening date have already been slated. “More power to them,” Della Femina responds. “As soon as they sign, and the check clears, we’ve got a deal.”
